Detective Chief Inspector Paul Fotheringham, who led the investigation into Ms Geldof's death, said: "The black bag also contained 34 medical syringes, some were with needles and some without, some were sealed in original packaging and some contained traces of a brown coloured residue.

"There were also 45 packaged and sealed syringes, alcohol wipes and cotton buds."

Police also found a pair of knotted black tights under Ms Geldof's body and two other pairs of tights with knots in them elsewhere in the property, likely to have been used while she took the drug.

The initial assessment of the scene found that Peaches had taken heroin and collapsed and died on the bed.

Detailed searches of the whole premises took place and located heroin and various items used for the preparation and consumption of heroin.

Next to the bed was a box containing a capped syringe with a small amount of a brown fluid left in the main chamber and some residue/fluid inside the cap - which forensics have found to contain traces of heroin.

Persons taking heroin on a regular basis develop a tolerance to the drug, and such individuals can use doses that would be toxic, or fatal, to people with no tolerance. However, tolerance to heroin (and other opiate drugs) appears to be lost fairly rapidly when users cease to use the drug, and deaths commonly occur in people who have previously been tolerant and have returned to using heroin”

Peaches Geldof hid her drug use from her husband, hiding heroin in the loft of their family, her husband Thomas Cohen told an inquest.

Mr Cohen told the hearing his wife had started taking heroin again in February and he had witnessed her flushing drugs down the toilet at their home in Wrotham, Kent.

The musician confirmed that he had gone to stay with his parents in southeast London with the couple's two sons, Astala, two, and one-year-old Phaedra, and that she had seemed fine when he spoke to her on several occasions over the weekend.

The inquest heard that Mr Cohen's father, Keith, had seen Ms Geldof when he dropped her youngest child home to her and she appeared fine. Mr Cohen said he had last spoken to his wife at 5.40pm on Sunday April 6.
